rawhide failed boot

Description of problem:
Updated a DL380 and DL385 from F10 to Rawhide.  Now they fail to boot because they can't find the root partition.

Version-Release number of selected component (if applicable):

How reproducible:
every time

Steps to Reproduce:
1. install F10
2. "yum upgrade" to rawhide
3. reboot
Actual results:
see attached rawhide-2.6.29-0.25.rc0.git14.fc11.x86_64.txt

Expected results:
see attached fedora10-

Comment 3 Aron Griffis 2009-01-27 13:15:01 EST
I added the following commands to the initrd:

find /dev/cciss
find /dev/mapper

Here's the resulting output:

a09428de-ba1f-47d1-bf30-80abe6842bbf/dev/cciss/c0d0p2 /boot 6c2d6985-57f1-4f88-9e2a-28800d53fe62

/dev/cciss/c0d0p7 /mnt/c0d0p5 57c6efcf-2b77-4033-90b4-f0d7b692bcae

So it appears that the cciss driver in the initrd is working correctly.  Next
suspect would be lvm's scanning.
Comment 4 Aron Griffis 2009-01-28 18:50:54 EST
Okay, setting sysfs_scan = 0 in /etc/lvm/lvm.conf allows the system to boot.  The problem is that lvm scans /sys/class/block to determine the validity of devices.  Here's what it sees on rawhide:

$ /bin/ls -lF /sys/class/block/ 2>&1 | grep cciss

and here is what it sees on f10:

It appears that the older cciss driver replaced the slashes with bangs to make the file valid.  The newer driver gets it wrong.
Comment 5 Doug Chapman 2009-01-29 17:24:10 EST
I am able to reproduce this even without LVM.  Also I don't think this is limited to cciss.  I think this is the same issue I was running into on big ia64 servers about 6 months ago.

Somehow these kernel config options got turned OFF in Fedora even though they default is 'y':


when I ran into this back then we had them turned on in the ia64 config file.  It appears that something in nash requires this in some situations.  Since nash is nearly (ok completely) impossible to debug I am not sure where to go with this.

Can we get these options turned back on in the Fedora kernel configs?  They always used to be on and default to on upstream.
Comment 6 Aron Griffis 2009-01-30 11:02:28 EST
Doug, I don't think CONFIG_SYSFS_DEPRECATED is related to this bug.  The lvm tools prefer /sys/class/block if it exists, so they'll ignore /sys/block either way.

Rather the problem was corruption in the /sys/class/block directory, seemingly caused by the cciss driver, though it could have been in generic code that the cciss driver calls.  I'm using the past tense because it seems to be fixed now in kernel-2.6.29-0.66.rc3.fc11.x86_64.  Looking at the kernel rpm changelog, I think the fix came from upstream, because there doesn't seem to be anything relevant to this problem applied by Red Hat.

Either way, glad to see it fixed.
Comment 7 Michael Cutler 2009-02-25 12:26:28 EST
I'm having the very same problem, on a HP DL380 G4 server upgrading from FC10 to Rawhide I get the 'kernel-PAE-2.6.29-0.145.rc6.fc11.i686' kernel, reboot the machine and it cannot find the root partition.

        initrd /initrd-

I tried two grub config's where the first was made by the RPM installation "root=/dev/VolGroup00/LogVol00" this failed, just out of curiosity I created a second grub boot line using the UUID instead "root=UUID=099c4b4e-7655-47d7-90d4-7fc9a3bfcc9d" neither boot the machine.
Comment 8 Michael Cutler 2009-02-25 12:44:25 EST
I've just repeated this test using 'kernel-PAE-2.6.29-0.137.rc5.git4.fc11.i686' and got the same problem. The boot fails saying:

  Reading all physical volumes. This may take a while...
  Volume group "VolGroup00" not found
Unable to access resume device (/dev/VolGroup00/LogVol01)
mount: could not find filesystem '/dev/root'
Comment 9 Aron Griffis 2009-02-25 13:06:20 EST
Michael: suspect your problem is different.  The problem in this bug is that the /sys/class/block/ entries were broken for cciss.  That's fixed now, as mentioned in comment 6

Rather I suspect the problem you're facing is that the cciss driver is being omitted from the initrd.  I don't know if there's a bug open for that presently.  Doug?
Comment 10 Milan Broz 2009-02-25 13:07:44 EST
updated lvm tools (since 2.02.29) works correctly with both old and new sysfs
structure, the bug here is problem with wrong device initialization in initrd

I saw similar problem when testing upstream kernel with
CONFIG_SYSFS_DEPRECATED_V2 set to off and I found that in mkinird is hardcoded
old sys path causing wrong drivers in initrd...
(and the drivers were not put into initrd at all)

For me this helps (but it is probably unrelated to your problem...):

Comment 11 Michael Cutler 2009-02-25 13:26:57 EST
Thanks guys, by recreating the initrd manually I have pushed the cciss driver in and the box is now working again on the latest rawhide kernel:

mkinitrd --with=cciss initrd-2.6.29-0.145.rc6.fc11.i686.PAE.img 2.6.29-0.145.rc6.fc11.i686.PAE

Comment 12 Hans de Goede 2009-03-09 05:37:08 EDT
I don't believe this is cciss related, but rather is an issue when upgrading from
F-10 to rawhide when using yum (rather then anaconda).

The problem is you are still running an older kernel when mkinitrd gets run. Yum upgrading is unsupported, but don't worry I agree this one is rather bad. So I'll fix it.

I'll dup this to the bug of tracking the general issue of running mkinitrd when
running an older kernel. Note that bug has a patch attached, so if you want you
can give that a shot.
